platform/x86: intel_punit_ipc: Fix resource ioremap warning
For PUNIT device, ISPDRIVER_IPC and GTDDRIVER_IPC resources are not mandatory. So when PMC IPC driver creates a PUNIT device, if these resources are not available then it creates dummy resource entries for these missing resources. But during PUNIT device probe, doing ioremap on these dummy resources generates following warning messages. intel_punit_ipc: can't request region for resource [mem 0x00000000] intel_punit_ipc: can't request region for resource [mem 0x00000000] intel_punit_ipc: can't request region for resource [mem 0x00000000] intel_punit_ipc: can't request region for resource [mem 0x00000000] This patch fixes this issue by adding extra check for resource size before performing ioremap operation.
